Paper Source/Feeding

Enable this to shorten the scanning time when scanning continuously.

"Pre-pick" refers to feeding the next document into the ADF before ejecting the current document being scanned when scanning documents continuously.

Enable

[Enable] is set to on as the factory default.

HINT

If you cancel in the middle of scanning while pre-pick is enabled, you have to remove the pre-picked document, then load the document again.
This setting can also be configured in the scanner driver.

Note that priority is given to the scanner driver setting.

Specify the number of feeding retries when a document is not fed from the ADF paper chute (feeder).

Number of paper feeding retries: The factory default setting is "3".

Multifeed is an error that occurs when two or more sheets are overlapped and fed at once.

Configure the settings to detect overlapped documents during a scan.

Overlapped documents are detected with the ultrasonic sensor or according to the difference in length of the documents.

When overlapped documents are detected, an error message is displayed on the touch screen and the scan stops. If documents are overlapped within 30 mm from the leading edge, they are not detected as overlapped.

Detection Method

Specify a method to detect overlapped documents.

Does not detect

Does not detect overlapped documents.

This is the factory default setting.
Check Overlapping (Ultrasonic)

Detects overlapped documents with the ultrasonic sensor.

When this is selected, you can specify the following two options:
- Specify an area to detect overlapped documents by the length from the leading edge of the document in the feeding direction.
  
  Set it in [Multifeed Detection Area].
- When a piece of paper is attached on a document, the length and position of the paper can be memorized, and set to ignore overlapping of documents.
  
  Set it in [Intelligent Multifeed Detection].
Check Length

Detects overlapped documents according to the difference in length.

Select this to scan documents of the same length.

Note that overlapped documents cannot be detected accurately when a mixed batch of different lengths are scanned.
Check Overlapping and Length

Detects overlapped documents by the combination of [Check Overlapping (Ultrasonic)] and [Check Length].

When this is selected, you can specify the following two options:
- Specify an area to detect overlapped documents by the length from the leading edge of the document in the feeding direction.
  
  Set it in [Multifeed Detection Area].
- When a piece of paper is attached on a document, the length and position of the paper can be memorized, and set to ignore overlapping of documents.
  
  Set it in [Intelligent Multifeed Detection].
Note that overlapped documents cannot be detected accurately when a mixed batch of different lengths are scanned.

Threshold (Length)

Specify the difference in length of documents to be detected as overlapped documents.

Overlapped documents are detected when the difference in length of documents is longer than the specified value.

Specify this item when [Check Length] or [Check Overlapping and Length] is selected for [Detection Method].

Any length under the specified value is tolerated as a slight error and not detected as overlapped documents.

10 mm or less is not detected

This is the factory default setting.
15 mm or less is not detected
20 mm or less is not detected

ATTENTION

To scan documents with different lengths, select [Check Overlapping (Ultrasonic)].
When an attachment such as a sticky note, receipt, or photo is attached on the document, the attachment part of the document may be detected as overlapping of documents if [Check Overlapping (Ultrasonic)] is selected. In that case, select [Check Length].

Otherwise, detect overlapping of documents by specifying an area on the document that does not include an area attached with paper in order to ignore the overlapping of documents for that area.

HINT

This setting can also be configured in the scanner driver.

Note that priority is given to the scanner driver setting.
When the Carrier Sheet setting is enabled in the scanner driver, the touch screen does not display the error message. The scanner driver does.

Specify an area to detect overlapped documents.

Specify this item when [Check Overlapping (Ultrasonic)] or [Check Overlapping and Length] is selected for [Multifeed Detection].

Enable

Specify whether to set an area to detect overlapped documents.

[Enable] is set to off as the factory default.

How to set the detection area

Specify whether to set a disabled area or enabled area to detect overlapped documents.

Set the disabled area

This is the factory default setting.
Set the enabled area

Start (mm)

Specify the start position of the detection area by the length from the leading edge of the document in the feeding direction.

The factory default setting is "0".

End (mm)

Specify the end position of the detection area by the length from the leading edge of the document in the feeding direction.

The factory default setting is "0".

HINT

When the start and end positions are both "0", overlapped documents are detected in the whole document regardless of the setting for [How to set the detection area].
To disable the detection of overlapped documents for the whole document, select [Set the disabled area] for [How to set the detection area], and set the start position to "0" and the end position to equal the document length or longer.
If the start position is set at the length that is longer than the document length, overlapped documents are detected in the whole document when [Set the disabled area] is selected for [How to set the detection area], and overlapped documents are not detected anywhere in the whole document when [Set the enabled area] is selected for [How to set the detection area].
To detect overlapped documents, the area must be at least 5 mm in length.

Configure the setting so that the value of the end position minus the start position is 6 mm or more.
For examples of the overlapping detection area settings, refer to Examples of the Settings for the Area to Detect the Overlapping of Documents.

Configure the setting to automatically ignore certain patterns of overlapped documents when the setting to detect overlapped documents is enabled.

Note that you first need to specify [Check Overlapping (Ultrasonic)] or [Check Overlapping and Length] in the scanner driver and "Multifeed Detection" on the touch screen before setting this item.

Operation mode

Set the operation mode.

Manually Bypass

Specify whether overlapped documents are detected when re-scanning documents detected as overlapped documents.

Does not memorize the size or location of the paper attachment.

This is the factory default setting.

Automatically Bypass (combination of length and position)

Specify whether the length and position of a piece of paper attached on a document detected as overlapped documents are memorized as an overlap pattern.

If the overlap pattern is memorized, documents with the same overlap pattern are not detected as overlapped documents from the next scan.

HINT

When [When powering off] in [Memorize overlap pattern] is enabled, the overlap patterns (only for the last eight sheets) will be memorized.

Automatically Bypass (length)

Specify whether the length of the longest piece of paper attached on a document detected as overlapped documents is memorized as an overlap pattern.

If the overlap pattern is memorized, a document with a piece of paper in the same length or shorter attached is not detected as overlapped documents from the next scan.

Memorize overlap pattern

When confirming image

Specify whether or not to memorize overlap patterns automatically when the window is displayed to check images for documents that were detected as overlapped documents.

[When confirming image] is set to off as the factory default.

When powering off

Specify whether or not to keep overlap patterns upon turning the power off.

When [When powering off] is set to on, keep overlap patterns upon turning the power off. Set this to on to use the same overlap patterns after turning the power on again.

[When powering off] is set to off as the factory default.

Overlap pattern

[Clear] button: Delete all the overlap patterns that have been memorized in the scanner.

HINT

When the setting for using the Carrier Sheet is enabled in the scanner driver, [Intelligent Multifeed Detection] is disabled.

Configure the settings when manually loading and scanning one sheet at a time.

When you scan by manually loading one sheet at a time, you can specify the waiting time (interval) for loading the next document in the ADF paper chute (feeder). This enables continuous scanning as long as you load a document within the specified time.

If the specified time is exceeded, the scan is finished automatically.

Continuous Feed Mode

Specify whether or not to enable the continuous feed mode.

Set [Continuous Feed Mode] to on to scan more than one document in succession manually.

[Continuous Feed Mode] is set to off as the factory default.

When Manual Single Mode is used, the setting for [Continuous Feed Mode] is ignored.

Timeout seconds

Specify the time period until which the scanner confirms that no documents are loaded in the ADF paper chute (feeder) (the interval between the last scan and the detection of whether the next document is loaded or not).

The factory default setting is "10".

HINT

When [Continuous Feed Mode] is set to on, the scanner will wait for documents to be loaded until the specified timeout time elapses even if you start scanning with no document in the ADF paper chute (feeder).
When the feed mode switch is set to Manual Single Mode, the scanner will wait for documents to be loaded until the specified timeout time elapses regardless of the setting for [Continuous Feed Mode].

Enable this mode to use the scanner at an altitude of 2,000 m or higher.

Low atmospheric pressure at high altitudes may lower the accuracy in detections for overlapped documents with the ultrasonic sensor.

Enable

Setting [Enable] to on for this item improves the accuracy to detect overlapped documents.

[Enable] is set to off as the factory default.
